Effective t-J model of pairing: singlet versus triplet
The t J model is regarded as a canonical model of spin-singlet pairing induced by the kinetic exchange interaction also responsible for an antiferromagnetic ordering in the strongly correlated narrow-band systems. In the orbitally degenerate systems both ferromagnetic and antiferromagnetic kinetic...

Digital Library of Periodicals of National Academy of Sciences of UkraineРезюме: | The t J model is regarded as a canonical model of spin-singlet pairing induced by the kinetic exchange
interaction also responsible for an antiferromagnetic ordering in the strongly correlated narrow-band systems.
In the orbitally degenerate systems both ferromagnetic and antiferromagnetic kinetic exchange interactions
occur. I brie y review the analogy between the singlet and triplet types of pairing, as well as draw some
general conclusions about the pairing induced by these exchange interactions. The general discussion is also
illustrated with a concrete case of a two-dimensional lattice with the spin triplet pairing. |
